The steaming summit crater of San Cristóbal volcano is viewed here from the top of Casita volcano, whose western crater rim forms the ridge at the lower left. The SW crater rim (upper left) is 140 m above the NE rim, reflecting the influence of trade winds on tephra deposition. The 500 x 600 m wide crater is elongated in an E-W direction, and is several hundred meters deep.
